Hi ! Again, maybe I don't understand anything but despite yours patches to Gnome-power-manager, I still have a black screen which I can't "exit" when I don't use the netbook for several minutes. Is it normal?

I can't replicate your problem here... or I misunderstood you.
When my netbook is in idle for several minutes the brightness is decresed, but the screen is still visible (ie not completely black as happens to you).
Perhaps you changed default values in gconf for gpm options?

Check if you have a local hotkeys configuration for your user. From the main post:

However, if you already have a local configuration in your user home for hotkeys, this has the precedence over the global one.
To use the global one, you need to delete the following configuration files in your home:

First of all, thank you very much for your great work! I really appreciate it.
I have installed certain packages from your PPA (mainly the nc10-scripts) and now Fn+F5 works like a charm.

However, I have encountered one issue - when trying to use the Gnome Brightness Applet in the panel, the X-Server freezes. It is only after a long time (some minutes) that it becomes responsive again. The context information for this applet then tells me "Cannot get laptop panel brightness". Trying to move the slider leads to a new freeze.

Thanks for the info. I don't use the brightness applet, I was not aware of this problem.
Installing back the official 'gnome-power-manager' from ubuntu repos fixes the problem, so there is something wrong in my package. I'll investigate it. For the moment, avoid using the applet, or retrocede the package to the official ubuntu version.

The only error messages I can find at a first glance is:

This is a problem with the current intel driver and there is not a solution for it yet.
Anyway, looking at various bug reports on launchpad, this error seems to be completely harmless.
